Great starter set for finding the right hoop size
Color: Gold, Size: 40-50-60mm
Bought these for my girlfriend and we both ended up really liking them. I actually liked that this set came with multiple sizes because it let her try different looks before deciding what size she likes most. It was a nice way to test things out before spending more money on real gold earrings. They look good, feel lightweight, and have been a fun way to figure out her preference.

Great value and super cute!
Color: Gold, Size: 30-40-50mm, Color: Gold, Size: 30-40-50mm
These earrings are a yellow gold which I like, and they’ve held up really well the past few days in the shower and with daily wear. These feel high quality and as long as you arent rough with the clasps, these should last you a long time. These are affordable for the quality. I don’t think these will tarnish, and they haven’t lost any shine. The ones in the picture are the smallest size, but I love the others too. They are comfortable to wear and very light weight, whereas others I’ve tried have been heavy or not sturdy enough for daily wear. I would definitely recommend buying these!

Lovely earrings
Color: Silver, Size: 20-30-40mm
These earrings are thicker than what I wanted but they are so lovely and packaged so nicely that I am not going to return them. I will gift them to someone instead.
